2. Soldering the headers
Before using your click
™
board, make sure
to solder 1x8 male headers to both left
and right side of the board. Two 1x8 male
headers are included with the board in
the package.

CapSense click
™
with its
CY8C201A0
IC is a
capacitive sensing module that takes human
body capacitance as an input and directly
provides the real time sensor information
via I
2
C output. The board contains capacitive
sensing elements (5-segment slider and
two buttons) as well as two LEDs. The
CY8C201A0
has high immunity against
radiated and conductive noise.

1. Introduction
Turn the board upside down so that
bottom side is facing you upwards.
Place shorter pins of the header into the
appropriate soldering pads.
Turn the board upward again. Make sure
to align the headers so that they are
perpendicular to the board, then solder the
pins carefully.
CapSense click
™
is an accessory board in
mikroBUS
™
form factor. It’s a compact and
easy solution for adding capacitive sensing
elements to your design. It features
CY8C201A0
capacitive controller and
capacitive sensing elements. CapSense
click
™
communicates with the target
board microcontroller via
mikroBUS
™
I2C
(SDA, SCL), AN and RST lines. The board is
designed to use 3.3 V or 5 V power supply.
LED diode (GREEN) indicates the presence
of power supply.
3. Plugging the board in
Once you have soldered the headers your
board is ready to be placed into desired
mikroBUS
™
socket. Make sure to align the
cut in the lower-right part of the board
with the markings on the silkscreen at
the mikroBUS
™
socket. If all of the pins are
aligned correctly, push the board all
the way into the socket.

6. SMD jumper
There is one zero-ohm SMD jumper
J1
used to
select whether 3.3 V or 5 V power supply is
used. Jumper
J1
is soldered in 3.3 V position
by default.
